With the increasing labor quantity the profit may increase after a certain quantity, which means the deficit will be substituted by the benefit in forge process of screw. So that through turnover to be established the benefit may be formed after turn point. Detail value is needed to calculate the field according to the curves between them. The TC and AC is the first factor to consider and then AVC and AFC which is second factor.

The mass of flywheel will incline as the punch speed inclines, it will decline as radius inclines. It would incline when the punch mould mass inclines. So it is chosen that big radius and small mould mass for saving cost of material and machine. The biggest mass of flywheel is about 1.3tons at 0.4m of radius and 6Kg of punch at the speed of 9m/s. So it is important for us to choose the punch mass. If it is 2Kg the biggest one will 400Kg at the speed of 9m/s at 0.4m. then choosing speed of punch is second factor. The rotation is first effect factor and then radius at last punch mass and its speed ie. n>r>m>v turn. Bigger force is big mass and speed in terms of energy conservation principle. So it is determined with bigger mass at certain speed.

The relation of labour and capital is investigated. It is found that labour will decrease with increasing capital and the same trend will be on the opposition. With the goods quantity increase they will become big. When the quantity is small like Q=8 the very little change will happen so it is considered that it is the least one. K(capital) is larger than L(labor) 3~20 times which expresses the K is more weight than L. It is formed in terms of small coefficient β. It can be controlled through K and L that goods quantity is chosen so that the precision one may be solved whilst they are modified in terms of simulation when K and L change. It is convenient to our engineers and financial staffs to check the progression every day to guarantee daily work quantity in terms of K and L.

In robot design and application the force and angle with angular speed is important so this study will model numerical simulation and discuss detail data to investigate their property. The force may increase as arm 1 angle increases whilst it may increase if angular speed increases in three freedoms. Meantime it will decrease if angular acceleration increases. It is found that with the angular speed increasing all three force may increase whilst the angular acceleration will cause its increase too in five freedoms. From these value it is observed that F1 is prior one to ensure the strength and fatigue life then F2 is second one to estimate its strength whilst F3 may be neglected. The force may increase as arm 1 angle increases whilst it may increase if angular speed increases in three freedoms. Meantime it will decrease if angular acceleration increases.

4D printing includes the fourth dimension of time with the traditional 3D coordinates. Three dimensional (3D) Fabrics and textile items that can change shape and function over time are categorized as 4D Textiles. This transformation is caused by a complex interplay between hybrid materials and the exposure of external stimuli. For 4D textiles, elastic knitted fabrics and shape memory polymer are desirable materials. Medical products, soft robotics, architecture, automotive, sports, clothing and more fields may benefit from 4D textiles. In this study, the concept of 4D Textiles is reviewed in brief.

The human resource is discussed on company. The former specialist need to train the later candidate in order to maintain future enterprise. So as to greater build in future the task has been urgent now so the rapid progression is needed in company. Because the creation is meeting the citizen more and more the high tech goods need the continuous and rapid support. Focus on the creative kinetic energy the technological development need repaid as soon as possible. Let training be prevail in many sides in China that may be significant thing to do by us so as to improve our creation. Big city is a demand by many people so the special train has been required by professional staffs and specialists. So as to elect civilization city many chances are needed to create too. Like general company and infrastructure has been increased to employ many staffs etc.

With the increasing labor quantity the profit may increase after a certain quantity, which means the deficit will be substituted by the benefit in forge process of screw. So that through turnover to be established the benefit may be formed after turn point. Detail value is needed to calculate the field according to the curves between them. The TC and AC is the first factor to consider and then AVC and AFC which is second factor. The profit point is 5.5 and 20.5 piece when labor is two. That means that in the scope of this field the profit may be available. When the labor and capital inclines the total cost will incline. Average cost is no proportion to total cost.

The mass of flywheel will incline as the punch speed inclines; it will decline as radius inclines. It would incline when the punch mould mass inclines. So it is chosen that big radius and small mould mass for saving cost of material and machine. The biggest mass of flywheel is about 10Kg at 0.1m of radius and 7Kg of piston at the time of 0.06s and crank length R=75mm and linkage length L=255mm. So it is important for us to choose the piston mass. If it is 5Kg the biggest one will 10Kg at the time of 0.06s and crank length R=80mm and linkage length L=245mm then choosing crank length is second factor.
